Abstract

The invention relates to an axle, especially with trailing arms, for motor vehicles and trailers. To associate a good suspension of the axle with an effective damping and improved cornering properties, the two wheel rockers (4) are coupled rotationally via at least one torsion-spring bar (11) which is not supported on fixed parts. Each wheel rocker (4) is supported on a longitudinal leaf-spring arrangement (9) via a bearing block (8), the bearing block (8) being guided shiftably on the leaf-spring arrangement (9) and the leaf-spring arrangement (9) longitudinally movably on the vehicle frame (1). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Achse, vornehmlich Längslenkerachse, für Kraftfahrzeuge, Kraftfahrzeuganhänger, wie z.B. Wohnwagen, landwirtschaftliche Anhänger oder sonstige Anhänger, bei der jeder am Fahrgestell oder am Rahmen des Fahrzeuges gelagerte Radschwinghebel mit seinem die Radachse tragenden Ende an einer Längsblattfederanordnung abgestützt ist.The invention relates to an axle, primarily a trailing arm axle, for motor vehicles, motor vehicle trailers, such as e.g. Caravans, agricultural trailers or other trailers in which each wheel rocker arm mounted on the chassis or on the frame of the vehicle is supported with its end carrying the wheel axle on a longitudinal leaf spring arrangement.

In der technischen Entwicklung der Achsen für Kraftfahrzeug-Anhänger ging man zunächst von der Starrachse aus, die ggf. über Blattfedern Ogegenüber dem Anhängerrahmen abgestützt war. Obwohl die Blattfedern Kräfte in allen Richtungen aufzunehmen in der Lage sind, führte die Entwicklung zu sogenannten Längslenkerachsen, bei denen Radschwinghebel um eine horizontale, quer zur Fahrtrichtung sich erstreckende Achse gegen die Wirkung von Rückstellfedern schwingen. Bei Anhängern 5mit gehobenen Ansprüchen, wie z.B. bei Wohnwagen, folgte dieser Entwicklung die Anordnung der Radachsen nach Art von Schräglenkern (DE-GM 7 835 540 und 7 835 541).In the technical development of axles for motor vehicle trailers, the rigid axle was initially used, which was possibly supported against the trailer frame by leaf springs O. Although the leaf springs are able to absorb forces in all directions, the development led to so-called trailing arm axles, in which wheel rocker arms swing about a horizontal axis extending transversely to the direction of travel against the action of return springs. For trailers 5 with high demands, such as In caravans, this development was followed by the arrangement of the wheel axles in the manner of semi-trailing links (DE-GM 7 835 540 and 7 835 541).

Soweit die Rückstellfedern als Gummifedern ausgebildet sind, weisen Odiese zwar eine hervorragende Federkennlinie und gute Dämpfungseigenschaft auf. Die Wirkung von Gummifederelementen ist aber in nicht unerheblichem Maße temperaturabhängig. Soweit metallische Drehstabfedern eingesetzt werden, ergab sich das Problem der Schwingungsdampfung.As far as the return springs are formed as rubber springs, O have these Although an excellent spring characteristic and excellent cushioning property. The effect of rubber spring elements is temperature dependent to a not inconsiderable degree. As far as metallic torsion bar springs are used, the problem of vibration damping has arisen.

Es ist ferner bekannt, als Längslenker ausgebildete Radschwinghebel an Blattfedern abzustutzen, wobei die Radschwinghebel lediglich drehbar im Rahmen gelagert sind (Le Caravanier, Nr. 83, 15.06.1979). Solche Anordnungen bedingen eine gelenkige Aufhängung der Langsblattfedern und weisen eine unzureichende Fahreigenschaft bei ungleichmäßiger Belastung des Fahrzeuges und bei Kurvenfahrt auf.It is also known to support wheel rocker arms designed as trailing arms on leaf springs, the wheel rocker arms being only rotatably mounted in the frame (Le Caravanier, No. 83, June 15, 1979). Such arrangements require an articulated suspension of the long leaf springs and have an inadequate driving characteristic when the vehicle is loaded unevenly and when cornering.

Vom letztgenannten Stand der Technik geht die Erfindung aus und setzt sich zur Aufgabe, eine Achse für Kraftfahrzeuge oder für Kraftfahrzeug-Anhänger zu entwickeln, die unter Abkehr von der eingangs erwähnten Entwicklungsrichtung den Ansprüchen an Temperaturunabhängigkeit und ausreichender Dämpfungswirkunggenügt und dennoch eine für gehobene Ansprüche ausreichende Fahreigenschaft des Anhängers gewährleistet.The invention is based on the last-mentioned prior art and sets itself the task of developing an axle for motor vehicles or for motor vehicle trailers which, while moving away from the development direction mentioned at the beginning, meets the requirements for temperature independence and sufficient damping effect, and yet has a driving characteristic sufficient for high demands of the trailer guaranteed.

Üoerraschenderweise konnte eine gelungene Lösung dieser Aufgabe dadurch gefunden werden, daß beide Radschwinghebel untereinander über mindestens einen Torsionsfederstab drehschlüssig verbunden sind, der nicht an ortsfesten Teilen abgestützt ist.Surprisingly, a successful solution to this problem could be found in that both wheel rocker arms are rotationally connected to one another via at least one torsion spring rod, which is not supported on stationary parts.

Mit dem Gegenstand der Erfindung werden somit zwei unterschiedliche Federsysteme eingesetzt. Die Radschwinghebel sind um ihre Schwingachse mit einem sonst nicht abgestützten Torsionsfederelement verbunden. Zusätzlich stützt sich aber der Radschwinghebel über den Lagerbock an einer Längsblattfeder ab, wobei es sich empfiehlt, den Lagerbock an der Blattfederanordnung ausweichföhig abzustützen.With the subject matter of the invention, two different spring systems are thus used. The wheel rocker arms are connected to an otherwise unsupported torsion spring element about their rocking axis. In addition, however, the wheel rocker arm is supported on the bracket on a longitudinal leaf spring, it being advisable to support the bracket on the leaf spring arrangement in an evasive manner.

Der besondere Effekt der Erfindung besteht in der Überlagerung der unterschiedlichen Federsysteme, wobei die Vorteile der Längsblattfeder mit den Vorteilen des Torsionsfederstabes kombiniert, aber deren Nachteile ausgeschaltet werden. Bei mehrlagigen Blattfedern wird deren Dämpfungseigenschaft ausgenutzt. Sind nur wenige Lagen vorgesehen, kann ein zusätzlicher Stoßdämpfer eingesetzt werden. Die Verbindung der Radschwinghebel mittels Torsionsfederstäben, die sonst nirgends abgestützt sind, führt dazu, die bei Kurvenfahrt oder einseitiger Lastverlagerung sich einstellende Verschwenkung des einen Radschwinghebels auf den anderen, entlasteten, Radschwinghebel zur Auswirkung kommen zu lassen mit der Folge, daß das entlastete Rad eine stärkere Bodenaufdrückkraft erhält und damit die Fahreigenschaften selbst bei extremen Verhältnissen wesentlich verbessert werden.The special effect of the invention consists in the superimposition of the different spring systems, the advantages of the longitudinal leaf spring being combined with the advantages of the torsion spring rod, but the disadvantages of which are eliminated. With multi-layer leaf springs, their Damping property exploited. If only a few layers are provided, an additional shock absorber can be used. The connection of the wheel rocker arm by means of torsion spring bars, which are not supported anywhere else, leads to the effect that the pivoting of one wheel rocker arm on the other, relieved, wheel rocker arm occurring when cornering or one-sided load shifting has the effect that the relieved wheel is a stronger one Maintains ground pressure and thus the driving properties are significantly improved even in extreme conditions.

Während man bei den bekannten Blattfederanordnungen, die meistens für Starrachsen Verwendung fanden (vgl. Reimpell, Fahrwerktechnik, 2. Aufl., S. 80) den Nachteil der Eigenreibung und -dämpfung beklagte, wird beim Gegenstand der Erfindung "dieser Nachteil" bewußt eingesdzt, um die für Fahrzeuganhänger erforderliche Dämpfung der Radschwinghebelbewegung herbeizuführen. Dadurch war es möglich, die Radschwinghebel untereinander mit Torsionsfederstäbe zu verbinden, die bekanntlich keine oder nur eine geringfügige Dämpfungswirkung besitzen.While the known leaf spring arrangements, which were mostly used for rigid axles (cf. Reimpell, Fahrwerktechnik, 2nd ed., P. 80), complained about the disadvantage of inherent friction and damping, "this disadvantage" is deliberately used in the subject matter of the invention, to bring about the damping of the wheel rocker arm movement required for vehicle trailers. This made it possible to connect the wheel rocker arms to one another with torsion spring bars, which are known to have little or no damping effect.

)Ein anderer Vorteil ergibt sich schließlich dadurch, daß die Radschwinghebel trotz extremer Belastung beim Durchfahren von Kurven mit hoher Geschwindigkeit oder beim Überqueren von Schlaglöchern, schlechten Straßen oder dergleichen, keiner mechanischen Deformation ausgesetzt sind, weil die auf die Radschwinghebel von den Rädern her einwirkenden ? Kräfte über die Blattfederanordnung aufgefangen werden, die nach allen Dimensionen hin belastbar ist.) Another advantage ultimately results from the fact that the wheel rocker arms are not subjected to any mechanical deformation despite extreme stress when driving through curves at high speed or when crossing potholes, poor roads or the like, because they act on the wheel rocker arms from the wheels ? Forces are absorbed via the leaf spring arrangement, which is resilient in all dimensions.

Weitere Merkmale der Erfindung sind in den Unteransprüchen definiert. Einzelheiten der Erfindung ergeben sich aus der Zeichnung. In ihr ist )die Erfindung schematisch und beispielsweise dargestellt. Es zeigen:

  • Fig.1: eine Seitenansicht einer Achse und
  • Fig. 2: einen Schnitt durch die Achse entlang der Linie II-II gemäß Fig. 1.
Further features of the invention are defined in the subclaims. Details of the invention emerge from the drawing. In it) the invention is shown schematically and for example. Show it:
  • Fig.1: a side view of an axis and
  • 2 shows a section through the axis along the line II-II according to FIG. 1st

Mit 1 ist ganz schematisch ein Rahmen bezeichnet, der den Längsholmen eines Fahrgestelles oder der Anhängeraufbauten darstellen kann. An diesem Rahmen 1 ist unmittelbar oder mittelbar ein Lagerschild 2 angeordnet, in dem sich eine Schwingachse 3 für Radschwinghebel 4 befindet. Diese Schwingachse kann in herkömmlicher Weise durch eine Hohltraverse, welche die Lagerschilde 2 miteinander verbindet, gebildet sein, in der die Radschwinghebel 4 drehbar gelagert sind. Wie die Fig. 2 zeigt, sind die Radschwinghebel 4 untereinander durch mindestens einen Torsionsfederstab 11 verbunden, der im übrigen nicht abgestützt ist.1 schematically designates a frame that can represent the longitudinal spars of a chassis or trailer structures. A bearing plate 2 is arranged directly or indirectly on this frame 1, in which there is an oscillation axis 3 for wheel oscillating levers 4. This oscillation axis can be formed in a conventional manner by a hollow cross-member, which connects the end shields 2, in which the wheel rocker arms 4 are rotatably mounted. As shown in FIG. 2, the wheel rocker arms 4 are connected to one another by at least one torsion spring rod 11, which is otherwise unsupported.

Die Radschwinghebel 4 tragen an ihrem freien Ende die Radachse 6. Beim Ausführungsbeispiel ist vorgesehen, daß eine Nabe 5 des Radschwinghebels 4 einen Zapfen trägt, auf dem die Nabe des Rades 7 gelagert ist.The wheel rocker arm 4 carries the wheel axle 6 at its free end. In the exemplary embodiment it is provided that a hub 5 of the wheel rocker arm 4 carries a pin on which the hub of the wheel 7 is mounted.

Mit dem freien Ende, beispielweise der Nabe 5 des Radschwinghebels 4, ist außerdem ein Lagerbock 8 verbunden, der sich an einer Längsblattfederanordnung 9 hängend abstützt. Die Enden der Langsblattfederanordnung 9 sind mit dem Rahmen 1 des Fahrgestelles bzw. der Anhängeraufbauten über Führungen 14 verbunden, so daß dort ein Ausweichen in Längsrichtung möglich ist. Da der Radschwinghebel 4 nur einen Freiheitsgrad um seine Schwingachse 3 hat, ist es zweckmäßig, den mit dem Radschwinghebel 4 mittelbar oder unmittelbar verbundenen Lagerbock 8 ausweichfähig an der Längsblattfederanordnung 9 abzustutzen. Zu diesem Zweck wird beim Ausführungsbeispiel der Erfindung vorgesehen, die Verbindung über Ösen 10 durchzuführen, die um die Langsblattfederanordnung 9 geführt sind, daher leicht montiert werden können, und die eine Ausweichbewegung des Lagerbockes 8 entlang der Längsachse der Blattfederanordnung 9 zulassen.With the free end, for example the hub 5 of the wheel rocker arm 4, a bearing block 8 is also connected, which is supported on a longitudinal leaf spring arrangement 9 in a hanging manner. The ends of the longitudinal leaf spring arrangement 9 are connected to the frame 1 of the chassis or the trailer superstructures by means of guides 14, so that evasion in the longitudinal direction is possible there. Since the wheel rocker arm 4 has only one degree of freedom around its rocking axis 3, it is expedient to deflect the bearing bracket 8, which is directly or indirectly connected to the wheel rocker arm 4, on the longitudinal leaf spring arrangement 9. For this purpose it is provided in the exemplary embodiment of the invention to carry out the connection via eyelets 10 which are guided around the longitudinal leaf spring arrangement 9 and can therefore be easily assembled, and which permit an evasive movement of the bearing block 8 along the longitudinal axis of the leaf spring arrangement 9.

Es empfiehlt sich, den Lagerzapfen 6 für das Rad 7 durch die Nabe 5 zu führen und als Lagerung für den Lagerbock 8 zu verwenden. Am Radschwinghebel 4 kann außerdem ein Hebelansatz 12 für den Anschluß 13 eines Stoßdämpfers vorgesehen werden, sofern dieses als erforderlich gehalten wird. Je weniger Lagen der Langsblattfeder 9 Verwendung finden, desto nötiger ist die Anordnung eines Stoßdämpfers.It is advisable to guide the bearing pin 6 for the wheel 7 through the hub 5 and to use it as a bearing for the bearing block 8. On the rocker arm 4, a lever extension 12 can also be provided for the connection 13 of a shock absorber, if this is considered necessary. The fewer layers of the longitudinal leaf spring 9 are used, the more necessary the arrangement of a shock absorber.

Wie besonders Fig. 2 zeigt, sind die beiden Radschwinghebel 4 über einen Torsionsfederstab 11 miteinander drehschlüssig verbunden. Dieser Torsionsfederstab 11 ist im übrigen nicht abgestützt. Wenn also ein Radschwinghebel 4 infolge starker einseitiger Belastung, insbesondere bei Kurvenfahrt, stark einschwingt, wird über den Torsionsfederstab mit einer gewissen Verminderung zufolge der Torsionsdeformation der andere Radschwinghebel 4 ebenfalls verschwenkt, was dort, wo eigentlich Radentlastung entstehen müßte, eine stärkere Bodenhaftung des Rades erzwungen wird. Infolgedessen ist die Fahreigenschaft we- sentlich verbessert.As particularly shown in FIG. 2, the two wheel rocker arms 4 are connected to one another in a rotationally locking manner via a torsion spring rod 11. This torsion spring rod 11 is otherwise not supported. So if a wheel rocker arm 4 swings heavily due to heavy one-sided loading, especially when cornering, the other wheel rocker arm 4 is also pivoted via the torsion spring bar with a certain reduction due to the torsional deformation, which, where wheel relief should actually occur, forces a stronger grip of the wheel becomes. As a result, the driving quality is significantly improved.

Der Torsionsfederstab 11 besteht beim Ausführungsbeispiel der Fig. 2 aus einem torsionselastischen Rohr 15, an dessen Enden je ein im Querschnitt prismatischen Ansatz 16 angeschweißt ist. Diese Ansätze 16 sind dreh-schlussig mit den Radschwinghebeln 4 verbunden.In the exemplary embodiment in FIG. 2, the torsion spring rod 11 consists of a torsionally elastic tube 15, at the ends of which an attachment 16 with a prismatic cross section is welded on. These approaches are turning 16 - conclusively linked to the Radschwinghebeln fourth

Mit den Naben der Radschwinghebel 4 sind außenseitig Hülsen 17 verschwei t, die über Lagerbüchsen 18 in einer starren Hohltraverse 19 gelagert sind. Der Innendurchmesser der Hülsen 17 ist stufenweise abgesetzt, um den Außenabmaßen des Torsionsfederstabes 11 Raum zu verschaffen.With the hubs of the wheel rocker arms 4, sleeves 17 are welded on the outside, which are supported by bearing bushes 18 in a rigid hollow crossmember 19. The inner diameter of the sleeves 17 is gradually offset in order to create space for the outer dimensions of the torsion spring rod 11.

Sind die Radschwinghebel 4 als Schräglenker ausgebildet, dann wird der Torsionsfederstab 11 parallel zur Radachse, aber außerhalb der Achstraversen mit Ansätzen der Radschwinghebel 4 verbunden.If the wheel rocker arms 4 are designed as semi-trailing arms, then the torsion spring rod 11 is connected parallel to the wheel axis, but outside the axle crossbars with approaches of the wheel rocker arms 4.
